Luohe where professional audio company Henan Jiaming Yang Zheng * City Market 1503 +71780 +75 www.69139139.com 1399 +229 +631 Milan sun, Unit 2, Building 5, 208 Sound Design technology relatively simple. To the speaker, for example, the basic completion of the design is the low frequency response and divider, it needs a certain amount of theoretical knowledge. Technically speaking, the ideal heavy burst system should be able to fully reproduce the input time-domain waveform. In other words, it is a linear system, and has a flat frequency response and pure delay linear phase shift, but in fact this is impossible. So the choice of the audio unit is very particular about the audio unit manufacturing knowledge. Sound system design, the unit's optional on not only subject to the technical requirements of timbre optimization and best replay it is also subjective auditory and heavy burst content of which ( divider and the design of the crossover point). Greatest manufacturers here sound unit. There are two main processing unit speaker factories in our country. One long-term adherence to self-development, production, because they know how good unit gold content and high value-added ingredients. Although the largest gains but also the most difficult. Another on an OEM basis and abroad to foreign countries in accordance with their own requirements place an order, the use of the foreign variety of advantages to develop their own products, which can also be regarded as a shortcut. Both methods require proficient unit's intrinsic quality (physical and auditory). I am not in favor of foreign direct purchase of the finished unit. Image (the so-called flagship Some manufacturers do it, this practice has become obsolete), in order to show their strength. Another sales made directly to the speakers in the country. Unfortunately, do not, is still relatively common, and are able to see in the previous exhibition.
